Siam Seaplane expands Don Mueang hub ahead of Thailand seaplane launch

Siam Seaplane opened an expanded operations office at Don Mueang International Airport in Bangkok as it builds toward Thailand’s first commercial seaplane network. The company also highlighted new pilot certifications and plans for routes in the Andaman Sea and around Bangkok.

Why it matters: - Siam Seaplane’s expanded hub is a key step toward launching Thailand’s first commercial amphibious seaplane network. - The move supports faster private aviation, water-access tourism and last-mile travel to resort destinations across the country. - The company’s pilot certifications and infrastructure plans signal that commercial operations are moving closer.

What happened: - Siam Seaplane officially opened an expanded operational office base at Don Mueang International Airport Terminal 1 in Bangkok on July 3, 2026. - The new facility serves as the company’s central operational command centre. - The opening was paired with a strategic update on the company’s route plans and water-landing infrastructure roadmap. - During the ceremony, guests also viewed an aircraft up close on the airport apron.

The details: - The expanded hub is designed to strengthen flight operations, improve guest services and support network growth. - Siam Seaplane plans to launch its initial network in two operating regions. - The Andaman Network would link Phuket, Phang Nga, Koh Yao Noi, Krabi, Phi Phi, Koh Lanta, Koh Lipe and Trang. - The Bangkok Hub Network would connect Bangkok with Pattaya, Prachuap, Hua Hin, Koh Samui, Koh Phangan, Koh Tao, Rayong, Koh Chang and Koh Kood. - Siam Seaplane says Bangkok departures could reach those destinations in about 1.5 hours. - The company plans to open a new operational hub in Krabi later this year. - The Krabi hub is intended to support future operations and the gradual rollout of the Andaman seaplane network.

Between the lines: - The Don Mueang expansion shows Siam Seaplane is building the ground infrastructure needed before commercial seaplane service can scale. - The route map points to a premium tourism strategy built around coastal islands, resort cities and high-value leisure travel. - The combination of Thai pilot training and foreign captains suggests the company is trying to balance local capability with international operating standards. - The timing also indicates Siam Seaplane wants to establish credibility with regulators, partners and premium travelers before the broader launch.

What's next: - Siam Seaplane will continue developing water landing sites and working through regulatory milestones. - The company expects to begin the gradual rollout of its Andaman network from the future Krabi hub. - Thailand’s first commercial seaplane network remains the stated long-term goal. - Siam Scenic, a sister brand, will continue offering land-to-land charter and scenic flights in Thailand.

The bottom line: - Siam Seaplane is turning a private charter business into the infrastructure base for a new premium aviation category in Thailand.
